True/False. A virus is classified as a microbe. Correct Answer True False What is the smallest biological unit of life? Your Answer: A cell A cell At a generalized level, all cells are comprised of what? Your Answer: nucleic acid, protein, lipids, and carbohydrates Macromolecules* *A student may also answer: Proteins, Lipids, Nucleic acids and Carbohydrates, but they must answer with all four to be fully correct. How many different types of amino acids are available from which to make proteins? Your Answer: 22 non-essential and 16 essential amino acids 20 Define an essential amino acid. Your Answer: An essential amino acid is an amino acid that the body does not make on it's own and must be ingested. An essential amino acid cannot be produced by the human body and as such must be take in from the environment through alternative sources (i.e) food. Where can the two major types of nucleic acids be found in the cell, and what are their roles? Your Answer: The two major types of nucleic acids can be found within the nucleus of a eukaroyotic cell. They are DNA (deoxyribonucleuic acid) and RNA (Ribonucleaic acid). DNA contains genetic and hereditary information and the RNA transcribes the information from the DNA for protein synthesis. While both DNA and RNA can be found in the nucleus (center of the cell), only RNA is capable of leaving the nucleus. DNA contains a vast amount of hereditary information and is responsible for the inheritable characteristics of living organisms. RNA is responsible for deciphering the hereditary information in DNA and using it to synthesize proteins. Complete the following RNA strand, and indicate how many bonds are formed for each complementary pair: 3’ GGUCAUCG 5’ 5’ CC AGC 3’ Your Answer: 3' GGUCAUCG 5' 5' CCTGTTGC 3' 8 bonds are formed within this complementary pair. 3’ GGUCAUCG 5’ 5’ CCAGUAGC 3’ There are 2 bonds formed between A and U, and 3 bonds between G and C. The plasma membrane (select all that are true): Restricts movement of materials in and out of the cell Is often a triple layer comprised of lipids Prevents essential nutrients from escaping Contains hydrophobic tails pointing outward Carbon, hydrogen, and oxygen atoms come together to form what primary macromolecule? Give an example.
